Abstract

A computer system, including a display screen and a direct input device such as a mouse, with a direct manipulation interface, through which the user can not only cause the computer to perform a predefined task by selectively indicating a symbol representing the task but also edit such symbols and their attributes by causing handle-like figures to appear on the screen near the symbol to be edited. The system is operable in two modes. One is a use mode for having a predefined task carried out and no handle-like figures are shown. The other is an edit-and-use mode wherein the user can cause the handle-like figures to appear or disappear but can also carry out every task that can be carried out in the use mode regardless of whether or not these figures are being displayed.

Claims

1. A computer system with direct manipulation interface, comprising:

a display screen;

a pointing means capable of indicating a position on said display screen;

image-producing means for displaying an image on said display screen, said image including one or more task-calling areas, each of said task-calling areas being individually selectable and each of said task-calling areas being associated with a predefined task to be performed by said computer system;

handle-generating means for generating one or more handle areas associated with and proximal to at least one said task-calling area on said display screen if a handle-generating signal associated with said task-calling area is generated, each of said handle areas corresponding to an interface-modifying operation to be performed by said computer system on said task-calling area, said handle areas being removable in response to a handle-removing signal;

editing means for causing said computer system to respond, if any one of said handle areas is selected, by effecting the task-calling area interface-modifying operation corresponding to said selected handle area; and

task-performing means for causing said computer system to respond, if any one of said task-calling areas is selected, by performing the predefined task associated with said selected task-calling area, when said handle areas are currently being displayed on said display screen.

2. A computer system of claim 1 wherein said task-calling areas are selectable by said pointing means.

3. A computer system of claim 2 wherein, if said handle area is selected, said handle area is selected by said pointing means.

4. A computer system of claim 3 wherein said handle-generating signal is generated by said pointing means.

5. A computer system of claim 4 wherein said handle-removing signal is generated by said pointing means.

6. The computer system of claim 1 further comprising:

a mode-selecting means for causing at least one portion of said display screen to operate selectably in a first mode or in a second mode, wherein said handle-generating means and said editing means are operational in said first mode but not in said second mode.

7. The computer system of claim 6 wherein said image-producing means causes handle symbols to be displayed at said handle areas, each of said handle symbols being representational of the interface-modifying operation corresponding to said handle area.

8. The computer system of claim 7 wherein said image-producing means causes task symbols to be displayed at said task-calling areas, each of said task symbols being representational of the task associated with the task-calling area.

9. The computer system of claim 8 wherein said image also includes one or more select boxes, each of said select boxes being paired with one of said task-calling areas, and wherein said pointing means generates said handle-generating signal associated with any one of said task-calling areas if said pointing device selects said select box paired with said any one of said task-calling areas.

10. The computer system of claim 9 wherein said pointing means is a mouse.

11. A method of operating a computer system having a display screen and a pointing device capable of indicating a position on said screen, said method comprising the steps of:

displaying an image on said display screen, said image including one or more task-calling areas, each of said task-calling areas being individually selectable and each of said task-calling areas being associated with a predefined task to be performed by said computer system;

generating one or more handle areas associated with and proximal to at least one said task-calling area on said display screen if a handle-generating signal associated with said task-calling area is generated, each of said handle areas corresponding to an interface-modifying operation to be performed by said computer system on said task-calling area, said handle areas being removable in response to a handle-removing signal;

causing said computer system to respond, if any one of said handle areas is selected, by effecting the task-calling area interface-modifying operation corresponding to said selected handle area; and

causing said computer system to respond, if any one of said task-calling areas is selected, by performing the predefined task associated with said selected task-calling area, when said handle areas are currently being displayed on said display screen.

12. The method of claim 11 wherein said task-calling areas are selectable by said pointing means.

13. The method of claim 12 wherein, if said handle area is selected, said handle area is selected by said pointing means.

14. The method of claim 13 wherein said handle-generating signal is generated by said pointing means.

15. The method of claim 14 wherein said handle-removing signal is generated by said pointing means.

16. The method of claim 11 further comprising the step of:

causing at least one portion of said display screen to operate selectably in a first mode or in a second mode, wherein said handle-generating means and said editing means are operational in said first mode but not in said second mode.

17. The method of claim 16 wherein handle symbols are displayed at said handle areas, each of said handle symbols being representational of the interface-modifying operation corresponding to said handle area.

18. The method of claim 17 wherein task symbols are displayed at said task-calling areas, each of said task symbols being representational of the task associated with the task-calling area.

19. The method of claim 18 wherein said image also includes one or more select boxes, each of said select boxes being paired with one of said task-calling areas, and wherein said pointing means generates said handle-generating signal associated with any one of said task-calling areas if said pointing device selects said select box paired with said any one of said task-calling areas.

20. The method of claim 19 wherein said pointing means is a mouse.
